Monitoring the attractiveness of a UNESCO World Heritage region

Frans Sijtsma et al - 2015Omschrijving: In the last decade the topic of governance has emerged in the protected area debate. A cornerstone was the 2003 IUCN World congress in Durban. There and in further discussions it was approved that knowledge about who to involve in is essential. This has also become very significant in the Wadden Sea area, which is a unique trilateral area, not only in terms of its high nature value, but also because of its diverse functions, structures and constitutions.

Estimates of exposure times in the Wadden Sea: a comparison of methods

Janine Nauw et al - 2016Omschrijving: The vertical tide in the Wadden Sea causes alternate flooding and drying of the intertidal flats, the duration of which is affected by wind surges, secondarily. To estimate, for instance, the potential growth of microphytobenthos and foraging time of suspension-feeding bivalves and benthos-feeding waders, it is important to have spatio-temporal data of these exposure times. In this study, we have compared two methods to determine the exposure times of tidal flats in the Dutch Wadden Sea.

Towards an effective survey design for population studies within the Wadden Sea

Kees Camphuysen et al - 2015Omschrijving: Population assessments are a primary component of wildlife conservation, but scientists are continuously under pressure to reduce survey cost. Survey design is therefore usually a trade-off between the scientific requirements of a study and the costs involved. In a relatively well studied area like the international Wadden Sea, comprehensive long-term datasets on population developments are available for numerous taxa.

Citizen Science, an overview of the current state, the possibilities and challenges and the opportunities for the future

Bas Engels - 2015Omschrijving: Having received a World Heritage status in 2009 the Wadden Sea is recognized as one of the most important intertidal areas in the World (Baptist et al, 2007; Koffijberg & Smit, 2013). The Wadden Sea is not a pristine nature area, but also used by man. This human use may harm the natural values of the Wadden Sea, protected under de Natura2000 regime. Both human use and natural values are monitored, and some of this monitoring is required by law. This monitoring is of great value for science, policy and proper management of this unique area.

Indicators of socioeconomic development in the Dutch Wadden area

Michiel Daams - 2015Omschrijving: This report is aimed to contribute to the understanding of the Wadden area’s socioeconomy. A robust long term monitoring framework for the Wadden area ideally builds on a sound knowledge-base of the socioeconomic system and an understanding of how the system’s functioning in the Wadden area is distinctive. Often this requires insight in processes that exceed the spatial scale of the Wadden area, since these may have a significant impact on developments in the Wadden area. This both general and Wadden-specific theoretical base can be used to derive meaningful indicators for socioeconomic development in the Wadden area.

Shorebird recruitment in the Dutch Wadden Sea

Bas Engels - 2015Omschrijving: The Wadden Sea is acknowledged as one of the most important tidal wetland area to breed, to moult, to spend the winter, or on migration.

Sampling methods, a comparison between benthos sampling programs at Balgzand

Jaap van der Meer - 2015Omschrijving: Two different annual sampling programs of the marine intertidal macrozoobenthos of the Balgzand area in the western Dutch Wadden Sea are compared for the years 2008-2012 in terms of estimates of mean numerical and biomass density of eight abundant species. The SIBES program that uses a regular grid reveals lower SE/mean ratios than the BD program that uses a transect approach, despite a lower sampling effort in terms of total surface area sampled. Yet, particularly biomass density estimates are much lower in the SIBES program, which only partly can explained by inadequate sampling depth. It is recommended that the strenght of each program, efficiency in one and accuracy in the other, are combined in the future.

Alien species in the Dutch Wadden Sea: policies and management

Deep feelings around a shallow coast.

Frans Sijtsma et al - 2012Omschrijving: The Dutch Wadden area is an internationally renowned natural area with World Heritage status. Its ecological uniqueness can be attributed to its shallow coastal waters. However, the Wadden area is also a rural area in search of competitive economic activity so as to provide employment to its population. The aim of the analysis is to ascertain the level of the contribution of tourism to different parts of the rural economy, and to examine which parts and aspects of the natural area are highly appreciated by visitors and thus may serve as immobile resources for the local economy.
